Description

PowerTap G3 HubThe G3’s design allows for a simple, straight-forward way to measure power. By mounting the strain gauges in an area where external forces, such as spoken tension, cannot impact power measurement, the PowerTap G3 is able to deliver +/- 1.5% accuracy ride after ride.

More than just a power meter, The G3 delivers speed, cadence and power with pin-point accuracy all in one product. And its ability to be easily switched between bikes means you’ll never miss a watt.

G3 HubI like that it's easy to switch from bike to bike. Once I built the wheel, setup was easy. It's reliable, super simple battery change, and accurate. I'm glad I went with PowerTap!

This product is long lasting with flawless qualitySeveral years ago I needed an affordable way to measure my ouput on the bike while training for my first Ironman. My Powertap Hub (Pro+) exceeded my expectations. The hub has paid for itself 3 times over since I purchased it. I've put a ton of miles (trainer and outdoors) on this hub and the power readings are just as accurate as the day I purchased it. This hub has made me train smarter and race stronger.

My 3rd PowerTap hub will not be my lastI bought my G3 to replace a stolen SL+ I'd purchased in 2013, summer of 2015. Before the prices came down so wonderfully. Even after paying a couple hundred dollars more I think pt hubs are a great value. I built the 24 hole G3 into a flo 30 rim. My 2011 SL+ has been in 3 rims and still works flawlessly, it's internals were updated by Saris when the torque tube went out. These hubs are a big investment but they are quality hubs akin to other high end hubs plus the high quality data they provide and their ease of use and interchangeability makes them, imho, the best power meter solution for my situation. The super low cost on the GS model makes me want to build up another wheelset.

Q & A

compatibility

Hello,
I have one bike with shimano 9 speed cassette and one bike with shimano 10 speed , is it compatible with both??
If so, do I need any spacers and if so, are the spacers provided?
Thanks,
Rob

Asked by: rob59

Yes, however you will require a 1.85mm spacer for the 9 speed cassette and an additional 1mm spacer for the 10 speed cassette.

would it be feasible to build one of these into an Ultegra 20 spoke rear wheel?

or would it be too flex?

Asked by: Sambo33

Go for the shimano version, recommend more spokes unless your in the 65kg range as the flanges are weak. Use sapim cx-ray or equiv to keep the weight down.

Will this power tap work with my Garmin Edge 500?

I can confirm that you will indeed be able to transmit information from this hub to your Garmin Edge 500. I hope this helps.

8 speed and Ambit2 compatibility

Hi,
I would like to know if an 8 speed Shimano cassette will work and also if the Suunto Ambit2 will be compatible with this hub,
Thank you!

Asked by: Fransix

This will be compatible with a Suunto Ambit 2. As for using an 8 speed cassette you would need to fit several spacers to fit the cassette correctly and ensure that the rear d&eacute;railleur is correctly aligned to avoid the chain slipping over the top of the cassette.

Probably a very stupid question but is this compatible with the Polar V800?

Asked by: Bandit74

I can confirm that the two devices can be paired together.
